Django Python noob - how do I get the NUMBER out of a Aggregate sum?

Question

I have a simple Aggregate:

    tot=PurchaseOrderLine.objects.aggregate(total=Sum('price'))
    return HttpResponse(tot)

This returns "total".

If I do:

    return HttpResponse(str(tot))

It displays "{'total': Decimal('321.60')}"

How do I get the NUMERIC var out of this!

Answer 1

tot=PurchaseOrderLine.objects.aggregate(total=Sum('price'))['total'] 
return HttpResponse(tot)
